规模化养殖废水处理工艺对污染物削减研究

The Research of Pollutant Reduction on Large-scale Aquaculture Wastewater Treatment

随着农村养殖业的集约化、规模化发展,养殖业污染已成为我国超过工业污染和生活污染的首要污染源。本文分析了几种常见的畜禽业废水治理方式,并在四川内江市的典型养猪场建立实例验证,通过问卷调查和实地监测相结合的方法对规模化养猪场不同处理工艺废水污染物削减效率进行了对比研究,通过调查发现沼气池+生化处理+人工湿地这一模式能够最大程度的减少规模化养殖场所产生的面源污染。

With the large - scale development of the rural farming, the pollution of aquaculture became the primary source which was more serious than both industrial pollution and normal pollution. Several common ways of waste water treatment were analyzed, and typical farms were built in Neijiang of Sichuan, and the different reduction efficiency of wastewater pollutants treatment was compared by questionnaire survey and monitoring. Non - point source pollution can be reduced by using the model of ＂biogas ＋ biochemical treatment ＋ artificial wetland＂.
